There are nearly 76 million millennials, Americans between the ages of 18 and 35. They are a powerful voting bloc. Jack Davis, a senior at Dominican University, watched Monday night's debate and is on campus to encourage his classmates.

"It's really important that people take the opinions they have on social media and talking with friends and take it to a vote and make something change for real," he said.

ABC7 Political Analyst Carla Marinucci says millennials are the big question mark in this election.
